I think that was me, asking for a backend interface a half year ago.
But I've lost somehow the answer :)

Anyhow, I have recently discovered my old OpenGL backend and
updated it to cairo 1.3.

My question is:
* Is there any possibility that a new backend (OpenGL) gets into official 
cairo (marked as experimental, of course)?
* Or how long does it take for a release of a backend interface (with all 
necessary internals, i.e. tesselation etc)?

I know, there is already glitz, but it's rather cumbersome to use and needs an 
additional dependency.
This new OpenGL backend is just a few lines long and would allow using Cairo 
with any existing OpenGL context.
